A method of loads assessment in the knee joint for ergonomic practice

Many studies have been published about spinal loads during various work activities, but few of them have looked at the knee joint loads. This study proposes a method of assessment of knee joint load, which allows a rapid estimation of the knee joint loads. A measurement of ground reaction forces and a recording of trajectories of characteristic points on the knee joint have been performed while walking on a flat surface and during stair descent, using the BTS-Elite system and Kistler force platform. 3D coordinates of the marked points, 3D components of ground reaction forces, and coordinates of their respective points of application have been the input data for calculating the knee joint centre, the loads in the medial and lateral compartments of the knee joint, the ligament loads and the total knee load.
